Toyota will begin production of its innovative steer-by-wire technology by the end of 2024, having already successfully previewed the system on the Lexus RZ.
The technology was first shown on the all-electric RZ last year and while sales of the EV have started, it is only currently available with a traditional steering system as the automaker irons out some of the issues of the steer-by-wire setup. One of the biggest changes made since the first prototypes is that the system now has a 200-degree steering ratio as opposed to a 150-degree steering ratio.

Autocar recently had the opportunity to test out the updated version of the system and says that “the new ratio makes the steering feel less nervous and urgent while also keeping its low-speed maneuverability.” The changes that Toyota has made are also said to make reversing much easier than it previously was.
It is understood that Toyota has received feedback from hundreds of people on the steering system and that it has been designed to meet strict legislation requirements in Europe and China. It will be first offered in the Lexus RZ and Toyota bZ4X and could offer over-the-air software updates in the future. Unfortunately, current legislation does not allow for such updates.
A number of other EVs will use the steer-by-wire system in the future. This will include Toyota and Lexus EVs underpinned by an innovative new architecture that Lexus showcased at the Japan Mobility Show with the stunning LF-ZC concept.

Lexus design chief Simon Humphries revealed that the system has opened up new possibilities for the interior designs of its future models.
“We want the interior to be as open as possible,” he said. “You can get rid of the ‘bits and pieces’ and interior panels don’t have to cover anything. Go steer-by-wire and there are fewer mechanical bits to hide. It gives more and more freedom.”
